Experimental investigation of the wake behind a cooled cylinder

An experimental channel intended for investigation of a wake behind cooled cylinder was designed and constructed in this work. The setup is measurements with air at low Reynolds numbers. measuring techniques based on the standard visualization fog generator constant temperature anemometry (CTA) were used. flow performance investigated two cylinders placed inside square cross section. One kept temperature, while second could be using water circuit thermostatic bath. dependency Strouhal number evaluated compared to literature data empirical correlations. concept an effective non-isothermal also applied. Unfortunately, considerable difference between preliminary detected. air-flow found have unsatisfactory high turbulence intensity. Consequently, some modifications current design are proposed.
